Method for preparing roasted fragrant and sweet components of red dates and application of roasted fragrant and sweet components of red dates to pipe tobacco

Abstract

The invention belongs to the technical field of tobacco spice, and particularly relates to a method for preparing roasted fragrant and sweet components of red dates. The method comprises the steps that a, the red dates are washed, decored and dried; b, ethanol extraction is carried out; c, membrane separation is carried out to remove macromolecular matter; d, the materials pass through a macroporous adsorption resin chromatographic column to separate and acquire effective ingredients. The roasted fragrant and sweet components of the red dates contain rich monosaccharide, disaccharide and multiple roasted fragrance and sweet ingredients (furan, furanone, pyrone, cyclopentenone and other compounds), after the roasted fragrant and sweet components of the red dates are applied to the cut pipe tobacco, joyful roasted fragrant and sweet smells can be given to the pipe tobacco, the remaining taste is sweet and comfortable, and the pipe tobacco meets the favor of tobacco product consumers in China better. According to the preparation process of the roasted fragrant and sweet components of the red dates, ingredients having side effects on smoking of the pipe tobacco in red date crude extract can be effectively removed, two kinds of effective ingredients are separated and enriched, and the optimal application effect is achieved through effective blending of flavorists. The preparation process is simple and easy to operate, the production process is economical and environmentally friendly, and the method is suitable for being applied to large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of spices for tobacco, in particular to a preparation method of roasted sweet aroma components of red dates and its application in pipe tobacco. The application of this technology does not change the existing processing technology of shredded pipe tobacco, and can increase the roasted-sweet aroma of shredded pipe tobacco when burning and smoking, increase sweetness and reduce irritation. Background technique [0002] Pipe tobacco is a tobacco product intended for smoking with a pipe. The main raw materials of pipe tobacco are sun-cured or air-cured and flue-cured tobacco, and mixed with appropriate amount of spices or vegetable oil. In recent years, the sales of cut pipe tobacco in foreign tobacco markets have continued to grow. Among them, from 2008 to 2011, the sales of cut pipe tobacco in the United States jumped from 3.5 million pounds to 30 million pounds (1 pound is about 0.45 kilograms). In 2013, S...

Problems solved by technology

At present, domestic spice manufacturers mostly use the traditional low-alcohol ethanol continuous extraction method to prepare jujube extract. This method has two major disadvantages: ① part of the natural jujube aroma is lost during the extraction process, and the aroma of the product is weak; ② except for the aroma components in the product , the main components are sugar, pectin and protein substances, so that the application of the product is subject to certain restrictions

However, the resulting product still contains more protein, hemicellulose, pectin, pigments and other substances, which will be cracked to produce some harmful components during the smoking process of pipe tobacco, and at the same time increase the irritation and miscellaneous gas of smoking, Affecting sensory quality (Song Peng. Microbial fermentation to reduce harmful components in cigarette smoke and improve cigarette quality[D]. Xi'an: Northwest University, 2008.; Chi Jingji, et al. Relationship between main chemical indicators of tobacco leaves and their smoking quality Correlation analysis of [J]. Yanbian University Agricultural Science Journal, 2006, 28(3): 208-210.)

Moreover, although the obtained jujube extract is rich in aroma (fruity, sweet, etc.), the roasted aroma is not outstanding, and it is not effective in improving the roasted sweet aroma of pipe tobacco and developing pipe tobacco products that meet the tastes of domestic consumers. significantly
